Revision history [back]

Hi, I renamed the main function of tshark.c as Tb_Main() Like the code in this link: https://github.com/AkibHossainOmi/wireshark/blob/master/tshark.c

specific code section :

int
main(int argc, char* argv[])
{
    // For debug purpose
    // argc = 4;
    // argv[1] = "-Tjson";
    // argv[2] = "-r";
    // argv[3] = "/home/omi/packet.pcap";
    char* result = Tb_Main(argc, argv);
    free(result);
    return exit_status;
}

I change it to,

int
main(int argc, char* argv[])
{
    // For debug purpose
     argc = 4;
     argv[1] = "-Tjson";
     argv[2] = "-r";
     argv[3] = "D:\\Windows\\files\\packet.pcap";
    while (1)
    {
        char* result = Tb_Main(argc, argv);
        free(result);
        printf("Ok\n");
    }
    return exit_status;
}

Now It is giving the exception,

Exception thrown: read access violation.
**arg** was 0xFFFFFFFFFFFFFFFF.

Having the exception in different line each time when I am running and debugging it.

Note: This is running in the first time successfully in most cases and getting exception. This tshark source is supposed to return a json string of a pcap file data by the function Tb_Main().

As long as I understood, the pointers are not initiated when I am calling the function more than once.

How can I fix it?
